You know Sam to put this in proper perspective,,if I took you to the
Western shores and showed you that there is a correlation between wind
strength and wave heights,the stronger the wind blows the higher the
waves,you would probably feel insulted that such an explanation is
even necessary yet here we have an entire group of people in
sci.astro.amateur who feel a desperate need to argue against the
correlation between latitudinal rotational speeds and twilight
lengths,the slower the speed away from the equator the longer the
twilight denoting a round and rotating Earth.In order to prevent
falling into dismay,I have to believe that all people are not
unresponsive to the enormity of the error and that they fully
understand that while the proof for rotation of the Earth through 360
degrees in 24 hours using known rotational speeds for each latitude is
simple and effective,it is only the beginning of cause and effect
applied to all areas where planetary dynamics and terrestrial effects
mesh.

Each individual has to look in the mirror and be prepared to accept
the level at which they choose to comprehend the correlation between
cause and effect,just as wind strength/wave heights takes no real
effort ,neither does the correlation between twilight length/
latitudinal speeds and people should be ashamed of themselves if they
continue to promote an alternative explanation just to save the crude
conclusion of 'sidereal time' .I would also like to think that people
would deal with the error in an urgent way rather than attempt to
defend the error created by Flamsteed.
